Definitions

  • the present invention relates to a system for delivering moisturizing liquid to the lips of a subject suffering from dry lips, for example, after undergoing surgery.
  • the present invention is a system for delivering moisturizing liquid to the lips of a subject suffering from dry lips.
  • a method for delivering moisturizing liquid to the lips of a subject can comprise the steps of: (a) providing an applicator for applying the moisturizing liquid to the lips of the subject; and (b) employing a support structure to support the applicator so that at least a part of the applicator is deployed to engage a recess between the lips of the subject without obstructing contact between the upper and lower lips of the subject.
  • the support structure is supported primarily by at least one part of the body of the subject.
  • the support structure is supported at least in part by contact with the cheeks of the subject.
  • the support structure is supported at least in part by engagement with features of at least one ear of the subject.
  • the support structure includes a clamp for clamping the support structure to a bed.
  • the support structure includes a base configured to be self-supporting when placed on a flat surface.
  • the applicator includes an absorbent material moistened by the moisturizing liquid.
  • the applicator includes a conduit with a plurality of liquid release apertures.
  • a liquid supply arrangement including: (a) a reservoir for containing a quantity of the moisturizing liquid; (b) a supply arrangement in fluid communication with the reservoir and the applicator for supplying the moisturizing liquid to the applicator.
  • the liquid supply arrangement is a gravity-fed liquid supply arrangement.
  • the reservoir maintains the moisturizing liquid at a pressure above atmospheric pressure, the pressure generating liquid flow to the applicator.
  • the reservoir is pressurized by the weight of a part of the subject's body resting on the reservoir, thereby feeding the moisturizing liquid to the applicator.
  • the applicator includes a reservoir for containing a quantity of the moisturizing liquid.
  • a system for delivering moisturizing liquid to the lips of a subject comprising: (a) a reservoir for containing a quantity of the moisturizing liquid; (b) an applicator for applying the moisturizing liquid to the lips of the subject; (c) a supply arrangement in fluid communication with the reservoir and the applicator for supplying the moisturizing liquid to the applicator; and (d) a support structure configured for supporting the applicator, wherein the applicator is configured for dispensing the moisturizing liquid onto the lips through contact with the lips without insertion of the applicator into the mouth of the subject, with the help of an absorbent material.
  • the present invention is a system and corresponding method for delivering moisturizing liquid to the lips of a subject suffering from dry lips.
  • FIG. 1 illustrates schematically a system, generally designated 10, and a corresponding method according to the teachings of the present invention for delivering moisturizing liquid 12 to the lips of a subject 14.
  • system 10 includes an applicator 16 for applying the moisturizing liquid to the lips of the subject, and a support structure 18.
  • Support structure 18 is arranged to support applicator 16 so that at least a part of applicator 16 is deployed so as to engage a recess between the lips of subject 14 without obstructing contact between the subject's upper and lower lips.
  • applicator 16 engaging the recess between the lips but without obstructing closure of the lips together, is highly advantageous.
  • the proximity of applicator 16 to the lips allows the use of simple contact-based implementations of applicator 16, thereby providing continuous and mess-free relief to the discomfort of the subject without requiring complex or expensive applicator devices.
  • by avoiding any obstruction to contact between the lips disruption of speech and other normal oral movement is avoided, thereby making the system as non-intrusive as possible.
  • an object located at least partially within the recess is referred to as "engaging the recess", without necessarily requiring it to be in contact with sides of the recess continuously.
  • the definitions refer to geometrical relations in two dimensions only, and particularly relating to an outline as viewed in a cross-section in the sagittal plane with the mouth closed.
  • the geometry of the human mouth is somewhat convexly curved in the side-to-side direction, and the recess referred to above may be an open-ended channel in three dimensions, or may otherwise change towards its lateral edges.
  • the various implementations of the present invention preferably include a reservoir 24 for containing a quantity of moisturizing liquid 12, and a supply arrangement, illustrated here as a fluid flow conduit 26, in fluid communication with reservoir 24 and applicator 16 for supplying moisturizing liquid 12 to applicator 16.
  • a supply arrangement illustrated here as a fluid flow conduit 26, in fluid communication with reservoir 24 and applicator 16 for supplying moisturizing liquid 12 to applicator 16.
  • Liquid 12 itself may be any non-toxic liquid effective for moistening the lips.
  • the liquid is typically water-based, and may have additives to provide a sweet taste or any other desired flavor, additives to improve efficacy for treatment of dry lips or any other desired additives.
  • additives may be in the form of a solution, a suspension, an emulsion or any other form. Most preferably, plain water is used. In certain cases, particularly where the subject is at risk of infection, sterilized water may be used. In many cases, regular drinking water may be sufficient.
  • Figures 3A and 3B show an enlarged view of applicator 16 deployed in engagement with the recess between the lips of a subject while the subject's mouth is open and closed, respectively.
  • applicator 16 is preferably kept in proximity to the lips during movement of the mouth, but does not obstruct normal opening and closing movement of the mouth, or any other motion of the mouth normally required for speech or facial expression.
  • system 10 as described schematically with reference to Figures 1-3B above may be implemented in a large number of practical implementations. More specifically, while maintaining the common functional features described thus far, each of applicator 16, support structure 18, reservoir 24 and supply arrangement 26 may be implemented in numerous ways. In order to give some indication of the scope of possible implementations, system 10 will be further illustrated with reference to seven non-limiting exemplary embodiments. The first three of these employ support structures 18 which are configured to be supported primarily by at least one part of the body of the subject, and most preferably, part of the head of the subject, thereby maintaining the desired position relative to the lips of the subject even if the subject moves around considerably.
  • FIG. 4A, 4B and 5 this illustrates a first embodiment of system 10 wherein support structure 18 is primarily supported by contact with the cheeks of subject 14.
  • support structure 18 is formed as a resilient frame 40, shown here with a roughly arcuate shape, with cheek contact regions 42 provided by grip elements 44.
  • Grip elements 44 are preferably formed from relatively soft resilient material, such as natural or synthetic rubber or silicone, which provide firm but comfortable grip on the cheeks of the subject. Grip elements 44 may be slidably mounted on the arms of frame 40 to provide adjustment of the size of the subject.
  • Frame 40 is typically formed from low-cost injection-molded plastic.
  • a central portion of frame 40 preferably includes a flattened region 46 which protrudes inwardly, forming a convex contour which contrasts with the generally concave curvature of the inside of the arcuate shape.
  • This portion provides support for, and defines the shape of, the applicator 16 of this embodiment, as will now be described.
  • Applicator 16 in this embodiment includes an absorbent material moistened by liquid 12 which serves to disperse the liquid over a desired contact area through capillary action. Liquid 12 is applied to the lips as they come into contact with the moistened absorbent material.
  • the absorbent material is implemented as a layer 48 of woven or non-woven cloth or open-cell foam material wrapped around flattened region 46 of frame 40.
  • Fluid flow conduit 26 which has one or more liquid release aperture 50, as revealed in Figure 4B .
  • a structure such as shown in Figure 4B , without absorbent material, may be used directly as an applicator, optionally provided with a plurality of openings to distribute the liquid more evenly across the lips.
  • Conduit 26 as shown here passes along one side of frame 40, typically held in place by a number of clips integrally formed with the frame, and extends around the inward-facing edge of flattened region 46 where aperture 50 is located. In this manner, fluid supply is ensured primarily to the absorbent material on the side of flattened region 46 facing the lips.
  • conduit 26 passes through a lateral opening formed in frame 40 so as to pass neatly from the outside to the inside of the arcuate frame.
  • Figure 5 illustrates the system in use with grip elements 44 gripping the subject's cheeks and applicator 16 engaged in the recess between the lips of the subject, but without obstructing contact between the lips.
  • the device of Figures 4A-4B may be used to advantage with substantially any form of reservoir 24 and liquid supply arrangement.
  • a gravity-fed liquid supply arrangement with a suspended flexible reservoir "bag” of a type familiar from intravenous drip (“I.V.”) arrangements is shown.
  • a simple flow regulating control 52 also of a type commonly used in I.V. sets, may be used to limit the flow rate to a suitable flow rate.
  • this and other embodiments of the present invention may include a flow limiting element 53 incorporated within conduit 26, or at any other point along the flow path, to limit the flow rate to a suitable level.
  • Suitable flow rate limiting elements may be implemented using well developed technology (e.g., flow labyrinths or pressure-regulating diaphragms) common in drip irrigation systems which provide a desired flow rate largely independent of variations in the supply pressure.
  • a capillary tube is incorporated within the flow path.
  • the capillary tube has an internal diameter of between about 0.05 mm and about 0.2 mm, and most preferably about 0.1 ⁇ 0.03 mm.
  • a length of the capillary is preferably between about 5 and about 30 mm, and most preferably about 8 ⁇ 3 mm.
  • Such a capillary can conveniently be attached at the end of conduit 26 or otherwise be deployed to define an outlet to applicator 16.
  • a glass capillary tube of internal diameter 0.1 mm and length 8 mm has been found effective when used with an infusion bag supply positioned 70-110 cm above the outlet to maintain flow rates of around 10 cc. per hour.
  • FIG. 6 there is shown an alternative embodiment of system 10, in this case employing a support structure 18 which suspends applicator 16 from a hat or head-band 60 substantially encircling the crown of the subject 14.
  • reservoir 24 is shown mounted directly on head-band 60.
  • reservoir 24 may have an opening 61 for convenient refilling of reservoir 24.
  • Applicator 16 may be suspended from head-band 60 via any suitable suspension arrangement.
  • one or more stiff arm is used to retain the applicator in place.
  • the arm may be deformable in order to allow repositioning of the applicator in the correct position for the subject.
  • conduit 26 may itself be implemented as a tube sufficiently stiff to provide the repositionable deployment as described.
  • Applicator 16 as illustrated here is a hollow body, typically of plastic, with an array of small openings for releasing liquid.
  • the size of the openings, as well as coatings or other surface properties of the applicator, may be chosen to provide drip-free retention of liquid at the openings through surface tension effects. Liquid is then released by contact against the lips of the subject.
  • support structure 18 is implemented with an eye-glasses-type support frame which engages at least one and preferably both ears of the subject 14.
  • support structure 18 also features a bridge portion lying across the bridge of the subject's nose.
  • reservoir 24 is positioning reservoir 24 over and/or behind the ears. In order to ensure comfortable balance between the two sides, it may be preferably to provide two similar reservoirs on opposite sides of the support structure, one resting on each ear.
  • flow conduit(s) 26 are preferably implemented as part of support structure 18, or as thin tubes passing within the structure. Flow from reservoirs 24 to applicator 16 is preferably achieved through capillary action drawing water through the fine tubes of support structure 18 to applicator 16.
  • Applicator 16 as shown here, best seen in Figure 7B is implemented in a manner conceptually similar to that of Figure 4A , with an absorbent material deployed around a tube with drop release apertures.
  • FIGS 8A and 8B there is shown an implementation of system 10 in which support structure 18 is an adjustable jointed stand with a base configured to be self-supporting when placed on a flat surface, such as the surface of a bed. This allows positioning of applicator 16 in an appropriate position for short term use by a subject confined to bed, such as for example while recovering from anesthesia. Applicator 16, shown more clearly in Figure 8B , is similar to that of Figure 6 .
  • a reservoir 24 is here provided at or near the base of stand 18, and is connected to applicator 16 via a conduit 26.
  • a driving force for supplying liquid to applicator 16 is provided by a spring-clamp 80 applied so as to apply pressure to external surfaces of flexible reservoir 24. The pressure of the spring-clamp maintains moisturizing liquid 12 within reservoir 24 at a pressure above atmospheric pressure, thereby generating liquid flow to the applicator.
  • FIGS 9A and 9B show a further variant embodiment based on a raised reservoir 24 mounted on a bracket 90 which holds it at a level above the subject by clamping to part of a bed frame.
  • Applicator 16 is here shown as a tube with a number of apertures formed at the end of a semi-rigid conduit 26 connecting applicator 16 to reservoir 14.
  • Figures 10A and 10B illustrate an implementation generally similar to that of Figures 8A and 8B , but in which reservoir 24 is pressurized by the weight of a part of the subject's body, in this case the head, resting on reservoir 24, thereby feeding the moisturizing liquid to applicator 16.
  • reservoir 24 may be located within or under a pillow to be used by the subject.
  • Applicator 16 itself is shown here as a single drop emitter mounted at the end of conduit 26.
  • reservoir 24 is formed as an integrated part of applicator 16.
  • the device is thus essentially a hanging reservoir 24 with an applicator 16 formed in its lower portion. The device is hung from a suitable stand, thereby achieving the desired positioning of the applicator 16 in the recess between the lips of the subject without obstructing contact between the lips.
  • Figures 4A, 4B and 5 may be implemented using a head mounted reservoir such as was shown in Figure 6 , or various other gravity-fed, pre-pressurized or body-weight pressurized reservoir arrangements.
  • a manually-operable supply e.g., a squeezable reservoir or a small manually-operable pump such as is common in liquid soap dispensers
  • a manually-operable supply also falls within the scope of the present invention.
